Troubleshooting for Failure in Starting Carburetor Reason Analysis: After the tryout, the carburetor has been exposed in the air for a long period, so that a layer of mucous membrane has formed and blocked the main jet. As a result, the oil canâ&#x20AC;&#x2122;t flow smoothly and the engine starting becomes difficult, or the engine stops soon after starting. Solvent: a. Check if there is any damage or leakage on the pressurized tube of oil cock; Pressurized Tube

b. Clean the carburetor and readjust the idle speed according to the steps below: a) Open the connecting tube between the air cleaner and carburetor.

Connecting Tube

b) Spray a little carburetor cleanser into the carburetor. Spray Cleanser

c) Start the engine and run for a while, then quickly step on the throttle pedal for several times .If the engine works well, assemble the connecting tube; otherwise, repeat the steps above several times. Readjust the idle speed if it is unstable.

3.1 Cylinder 3.1.1 Cylinder Removal The removal can be done on the vehicle body. a) Remove the cylinder head; b) Remove the cylinder; c) Remove the cylinder gasket and bolts; d) Clean the cylinder gasket.

Donâ&#x20AC;&#x2122;t damage the bond area of the cylinder. Donâ&#x20AC;&#x2122;t drop sundries like the cylinder gasket material into the crankcase.

3.1.2 Cylinder Inner Wall Wear Inspection Use a bore diameter dial gauge to measure the degree of wear. The measuring point is divided into three sectional planes in the axial direction: upper, middle, lower. Measure every plane each time on the mutually perpendicular directions (X, Y). The least measured dimension is the cylinder bore, the data measured at the most upper position is the largest diameter, and the data measured at the lower position is the smallest diameter. At the same cross section, measure the difference of diameter between the two points mutually perpendicular, which is the circularity of the cylinder.

In order to make the measuring point perpendicular with the bore axis of the cylinder, and to ensure the precision of the measurement, the bar of the gauge can be slightly swung in the direction of the gauge bar, and take the smallest reading number as the result.

In the situation without a dial gauge, a feeler gauge can be used to make the relativity measurement. Put a new piston into the cylinder, and use the feeler gauge to measure the gap between the piston skirt and the cylinder wall, and then figure out the abrasion loss of the cylinder. If the circularity of the cylinder exceeds the limit, a cylinder-reboring machine should be used to re-bore the cylinder, and to enlarge its diameter by 0.50mm or 1.00mm, then fit the piston and piston ring whose sizes are also enlarged. 16

3.4.1 General Introduction The four-stroke engine completes its four strokes with one piston stroke. The four strokes: Intake stroke, Compression stroke, Expansion stroke, and Exhaust stroke. 3.4.2 Valve Clearance Adjustment The valve clearance is an important technical parameter. Make sure that the valve can closely tightened under any conditions, especially when the engine is overheated; there must be certain clearance kept when the valve is in the cold condition. This clearance is called the valve clearance. When the engine is running, the valve clearance should be neither too big, nor too small. So the valve clearance adjustment is an important procedure in the valve maintenance. a) Remove the cylinder head cover. Inspection and adjustment must be done in cold conditions (below 35째C).

b) Turn the cooling fan clockwise until the mark of the timing drive sprocket on the camshaft is at the top dead center, and the "T" symbol (or other mark) of the magneto flywheel aligns with the crankcase mark. The crankshaft should co-rotate; otherwise the exhaust port may not be adjusted. c) When adjusting, loosen the lock nuts; adjust the bolts with a valve-adjusting wrench; if turning clockwise, the valve clearance decreases; and if turning counterclockwise, the valve clearance increases. d) Then, put a feeler gauge with the specific size between the valve and rocker to check for correct clearance. e) Take out the feeler gauge; tighten the lock nuts, and then inspect the valve clearance again.

Raider-Classic 150 (Oil-cooled&Internal Gearbox): Service Manual (single/ double-seat)

EEC Version;3.0 Feb..2005

Sometimes when tightening the lock nuts, it will change the clearance. So it must be rechecked for the proper clearance.

Valve clearance

0.06~0.07 mm

3.5 Camshaft The camshaft is a main driving unit of the valve train. There are the air inlet cam, the exhaust cam, and the cam journal on the shaft. It controls the intake and exhaust valves to open and close at the correct time. The camshaft wear will affect the engine performance and cause excessive noise. 3.5.1 Removal a) Loosen the valve cover bolts and remove the cover.

b) Remove the cam chain tensioner screw and the O-ring.

c) Tighten the cam chain tensioner-adjusting bolt clockwise. d) Turn the flywheel counterclockwise to make the "T" mark on the flywheel align with the mark on the crankcase. When the hole on the cam chain (timing drive chain wheel) is up, it is the top dead center position. e) Remove the cylinder head positioning bolt; Remove the camshaft holder bolt cap and washer.

Raider-Classic 150 (Oil-cooled&Internal Gearbox): Service Manual (single/ double-seat)

EEC Version;3.0 Feb..2005

f) Remove the camshaft holder and dowel pin; Remove the cam chain wheel from the cam chain, and remove the camshaft.

3.5.2 Inspection a) Inspect the camshaft bearings for play. If there is any play, replace the whole set; b) Inspect the cam surface for damages; c) Measure the height of the cam. Inlet Cam

25.96 mm

Exhaust Cam

25.815 mm

3.5.3 Installation a) Rotate the flywheel to align the "T" mark on the flywheel with the camshaft mark. At this time, the round hole on the cam chain wheel should be up, and the left and right should be parallel with the cylinder head (the lobes of the camshaft are down). b) Install the camshaft on the cylinder head; Mount the cam chain on the cam chain wheel; Install the dowel pins. b) Mount the camshaft holder, washer, and nut on the cylinder head; Tighten the cylinder head bolt and nut. While installing, first apply some oil on the thread part of the camshaft holder bolt. The camshaft nuts should be tightened diagonally in a 3-step process. After installing, adjust the valve clearance. c) Turn the cam chain tensioner adjusting bolt anticlockwise and release the lock; Apply some oil on the new O-ring; Mount and tighten the cam chain tensioner cover bolt. The o-ring must be mounted properly in the groove. 26

When the abrasion causes the valve seat width uneven, too wide or too narrow, it will result in bad contact between the valve and valve seat, and can’t seal tightly. At this time, it must be reamed with a customized valve seat-grinding cutter.

Raider-Classic 150 (Oil-cooled&Internal Gearbox): Service Manual (single/ double-seat)

The valve seat-grinding cutter is the customized trimming tool for the valve seat, and it has three cutting angles: 32º, 45º, and 60º. While trimming, press the valve seat-grinding cutter to make the rotary motion with 40 - 50N force. Some oil must be applied on the valve seat-grinding cutter to eliminate scraps when trimming.

3.9.2 Finishing a) Ream out the defects on the working surface with a 45º coarse tooth-grinding cutter.

Don’t ream too much.

b) Ream the upper angle of the valve seat working surface with a 30º grinding cutter.

c) Ream the lower angle of the valve seat working surface with a 60º grinding cutter. d) Ream the valve seat to the specific seat width with a 45º grinding cutter.

3.9.3 Touching Position Inspection a) Apply a thin layer of the fluid on the valve seat, and put the valve on the seat rotate joint, then take out the valve and observe the contact surface on the valve face.

EEC Version;3.0 Feb..2005

b) If the contact position is too high, then cut out some of the upper part of the valve seat with a 32º grinding cutter to reduce the working face of the valve seat; if the contact position is too low, then cut out some of the lower part of the valve seat with a 60º grinding cutter to raise the working face of the valve seat. c) Finally, grind the working face of the valve seat to the specific width with a 45º grinding cutter. If the valve seat still can’t contact evenly with the valve after trimming, the valve should be revised or replaced.

3.9.4 Valve and Valve Seat Lapping After finishing, the valve and valve seat should be lapped in order to make them seal properly. Spread a thin layer of the silicon carbide on the working bevel of the valve, and repeatedly rotate the valve suction cup to lap the valve and valve seat evenly until they match tightly. Before lapping, clean the valve, valve seat and valve guide. When lapping, don’t use too much force. During lapping, don’t drop any silicon carbide into the place between the valve lever and the valve guide. 3.9.5 Inspection of Valve and Valve Seat Air Impermeability After lapping the valve and valve seat, the air impermeability of their joint surface should be inspected. Method one: the same as the method of "valve seat contact position inspection”. Method two: evenly draw several lines on the working surface of the valve with a pencil. Put the valve into the valve seat, if the lines are all broken after turning 1/8 - 1/4 rings, then it shows the air impermeability is good. Method three: mount the valve on the cylinder head, and fill the inlet and exhaust vents with non-flammable solvent, and preserve for 5 minutes. If there is no leaking, the valve is seated correctly. 32

3.19 Belt Driven CVT Mechanism 3.19.1 General Introduction The belt driven CVT mechanism is made up of two belt pulleys (the drive belt pulley and the driven belt pulley) whose diameter can be changed, and a notched driven belt. The driving belt pulley is mounted on the engine crankshaft, and the driven belt pulley connects with the rear driven mechanism.

Its basic operational principle is to realize the automatic CVT by the diameter changes (the transmission ratio changes) of the driving and driven belt pulley. 48

Raider-Classic 150 (Oil-cooled&Internal Gearbox): Service Manual (single/ double-seat)

EEC Version;3.0 Feb..2005

When the diameter of the driving belt pulley changes form small to big, proportionally the diameter of the driven belt pulley changes from big to small (because the perimeter of the driven belt is constant). AT this time the speed increases; on the contrary, the speed decreases.
